What is an ISBN?
ISBN stands for International Standard Book Number and is a 13-digit number that uniquely identifies books and writing-related products.
How many ISBNs do I need?
A single ISBN will cover 1 format of 1 book. So if you’re publishing 1 book in paperback and ebook format, you’ll need 2 ISBN numbers.
Do ISBNs Expire?
ISBNs do not have an expiration date. Once you purchase an ISBN, it will stay in your account forever.
I’m planning to publish in the future. Should I buy my ISBN now, or wait until I’m ready to publish?
You can purchase the ISBN at any time.
Is the charge for the ISBN a recurring or one-time fee?
ISBN only require a one-time fee. There are no recurring charges.
